Recently Google released the official API for Google Fusion Tables. If you are not familiar with GFT here’s a brief introduction:
Google Fusion Tables is a product launched in Google Labs. It’s a free service for sharing and visualizing data online. It allows you to upload data, share and mark up your data with collaborators, merge data from multiple tables, and create visualizations like charts and maps.
With the new API, you can update and query a dataset in Fusion Tables programmatically. The API means you can import data from whatever data source you may have, whether a text file or a full-powered data base.
